Disclosed are a heat transfer medium and a heat transfer method that uses the heat transfer medium. The heat transfer medium comprises a light-transparent substrate coated with a plurality of nano particles. The nano particles absorb light incident thereon to thereby produce heat, which is transferred to a target object to be heated. Nano particles can be applied onto a target object. After heating, the particles are removed by etching. Nano particles can be selectively applied to the light-transparent substrate or directly to a target object to be heat so as to localize heat-production and thus heat selective portions of the target object.

A carbonization catalyst for forming graphene may be exfoliated from a graphene sheet by etching. A binder layer may be formed on the graphene sheet on which a carbonization catalyst is formed, to support and fix all or part of the graphene sheet. Further, the graphene sheet from which the carbonization catalyst is exfoliated may be transferred to a device. When exfoliating the carbonization catalyst from the graphene sheet, an acid may be used together with a wetting agent.

A method of fabricating a liquid film is provided. The method comprises the steps of applying hydrophilic liquid onto a substrate with an electrode formed thereunder, covering the hydrophilic liquid with a protection film comprising hydrophobic liquid, dispersing surfactant for reducing the surface tension between the hydrophilic liquid and the protection film, and applying voltage to the hydrophilic liquid and the electrode to wet the substrate with the hydrophilic liquid. With the surfactant and the electro-wetting principle, a contact angle between the hydrophilic liquid and the substrate is controlled. The liquid film having a uniform thickness in nano size is thus formed on the substrate. The protection film prevents the evaporation of the liquid film in the air to thereby secure the stability of the liquid film.
